Does anyone know how I can force Mathematica to display surds in the
numerator of an expression, or a function that can be applied to do the job?
For example, FullSimplify[1/(3+Sqrt[2])] returns itself and not 1/7
(3-root2)
Similarly, Sin[Pi/12] returns (-1+root3)/(2root2) and not 1/4 (root6-root2)
Many thanks
Tony
